DUMPING-VVAGON.

Application filed February 13, 1908.

Specification of Letters Patent.

Patented Aug. 29, 1911.. Serial No. 415,781.

To all whom it may concern.

Be it known that I, EDGAR B. SYMONS, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Dumping- VVagons, of which the following is a specification.

My invention relates to dumping wagons.

It is illustrated in the accompanying drawings wherein Figure 1 is a longitudinal section, Fig. 2 a. detail section, Fig. 3 an end view with parts broken away, Fig. 4 a cross section, Fig. 5 a plan view.

Like parts are indicated by the same numeral in all the figures.

1 1 are the rear wheels connected by the axle 2, and 3 3 are the forward wheels connected by the axle 4.

5 is the tongue and associated parts on which rests the fifth wheel'6 in the midst of which rises the conical pin 7 with the overhanging top 8.

9 is a plate provided with the perforation of such size as to let the top 8 pass, and associated with the plate 9 are the transverse bars 10 10, on which rests the forward end of the wagon.

The wagon bed proper consists of the side plates 11 11 of sheet metal and the surrounding angle iron edge pieces 12 12. At the rear, each of these side pieces rests in an angle bar 13, which forms part of or is supported on a bracket 14 which is secured rigidly upon the axle 2 by the bolts 15 15. The forward ends of the side plates rest upon the cross bars 10 10 and are properly secured thereto.

16 is the tail board rigidly secured in any desired manner to the side plates and provided with an upper outwardly projecting top board 17. 18 is the front part of the wagon body also provided with a. similar outwardly and forwardly projecting upper portion 19.

On each side of the wagon and above the side board is hinged an upper side board 20, by means of the hinges 21 21, and these hinged upper side boards are normally held in their elevated position by the latches 22 22. A foot board 23 is placed across the front and from it rises the angle irons 24 24 on which is supported the seat 25.

I shall now describe the dumping mechanism.

The bottom of the wagon consists on each side of an outer bottom board 26 26, preferably inclined as indicated, and hinged by the hinges 27 to the bottom of the side board. its inner edge rests upon a second or inner section 28 of the bottom. This section is, like the other parts of the wagon, of sheet metal, but is preferably turned at 29 or around its edge to strengthen it. Near the extreme inner edge of this section is secured the longitudinal bar 30 with the loops 31 31 to provide eyes along the bottom of this bar. The bar is preferably metal plated at 32.

The structure for the other half of the bottom is exactly the same and the parts are indicated. by the same figures, but in this case the extreme inner edge of the inner bottom section is preferably turned as indicated at 33. The two inner bottom sect-ions are supported each at each end by an elbow 34, one arm of which is preferably secured to the upturned end 35 of the inner bottom section 28. The other end of the elbow is pivoted at 36 to the hanger 37 rigid on the end of the wagon. Each of the inner sections is similarly supported. The two inner sections are held in position by means of the chain 38 38, the two branches of which pass under and along the bars 30 and through the loops or eyes 31 thereon. The middle portion of the chain passes around the pulley 39 in the hanger 40 on the rear end of the wagon. One section of the chain is connected to the tension spring 41 which is attached at the point 42 to the rear of the wagon. The two ends of the chain are wrapped around the drum 43 which is mounted so as to rotate between the two sides of the wagon and in front of the wagon box. They are crossed at the forward end of the wagon box as indicated at 44 and their ends are secured to this drum in any desired manner at the points 45. On one end of the drum is the ratchet wheel 46. To engage this ratchet wheel, rotate the drum and wind up the chain, I provide the lever 47, which carries the pivoted dog 48, the lever being pivotally mounted about the case of the drum 43. On the side of the wagon is placed a stop 49 which engages the lower edge of the dog to keep it out of engagement with the ratchet when the lever is in its lowest position, as indicated in Fig. 1. lVhen the lever is raised the dog falls backwardand engages the teeth of the ratchet. To stop and hold the ratchet in any desired position, I provide the foot lever 50 which is provided with the foot piece 51 and the stop piece 52. To itis pivoted the reciprocating bar 53 which carries the dog 54, pivotally mounted on the bar, provided with an engaging finger above and a balancing weight 55 below. The reciprocating bar 53 is pivoted in the hanger 56 which hangs from and is pivoted on the drum. hen the parts are as shown in full lines, the ratchet wheel is stopped and held and when they are as shown in dotted lines, the ratchet wheel is free to rotate.

It will be understood that the illustration is to be considered as diagrammatic and I do not wish to be limited to the particular forms shown, as the structure can be altered greatly without departing from the spirit of my invention.

The use and operation of my invention are as follows:

The connection between the wagon and the forward wheeZs.A dumping wagon is liable to be used on very rough and irregular surfaces and it often happens that the forward wheels are greatly displaced and frequently the wagon becomes uncoupled from the forward wheels or truck. I obvlate this by providing the conical coupling pin with outwardly projecting top or cap' and associating it with a perforated plate on the wagon body or frame. The relation between the two is such that the plate snugly fits the cap or top and, therefore, when the two parts of the wagon are inclined with reference to each other, the perforated plate is tipped and cannot be removed from the coupling pin in its inclined or tilted position. The upper end will invariably strike the under part of the cap.

The damping parts of the wag0n.-A dumping wagon which dumps as most of them do immediately below the body, should be adapted to pass backward or forward over the dumped material without making engagement therewith except with the wheels. In other words, the folding or dumping parts of the wagon should descend as little as possible toward the dumping material. I accomplish this by dividing the dumping bottom of my wagon into two pairs of sections. On each side of the middle hne, I have an inner and outer section. The inner edge of the outer section preferably hes on top of the inner section. Now when the parts are released it is evident that the weight of the material will tend to force the inner section down until it hangs in a position where its lower edge is approximately in line with its pivotal point. In this descent, however, the outer section, riding upon, tends to scrape and clean the bottom of the inner section, and the pressure of the load on the outer section forces it down, thus forcing back or outwardly the inner section until the parts assume the position shown in dotted lines in Fig. 4, that is until the two sections of the bottom are folded together and lie in vertical planes side by side, the inner sect-ion being now outside the outer section. Thus the two pairs of bottom sections are manipulated so that the entire bottom of the wagon is open, the sections are folded so that they extend the least possible distance, they are close together and they lie in vertical planes so long as any material is present to hold them. It is obvious that the wagon may now be moved forward clearing the material dumped with the greatest possible ease.

The mechanism for manipulating the damping b0tt0m.Assuming that the parts are in the position shown in the figures in full lines, the situation would be as follows: The chain is drawn tight up, the double sections of the bottom are held securely in position and there is a little pressure applied to the spring 41. If now pressure be applied to the foot piece 51, it will move forward in the position shown in dotted lines, the reciprocating bar 53 being forced forward so that-the dog 54 escapes from the ratchet wheel assuming the upright position shown in dotted lines. Since nothing holds the ratchet wheel, the drum unwinds and the bottom parts assume the position shown in Fig. 4 in dotted lines, and the load is dumped. WVhen now it becomes necessary to restore the dumping bottom to the position shown in full lines, the pressure on the foot piece 51 is released and the parts tend to resume the position shown in'full lines. The hand lever 47 is manipulated so that the dog 48 engages the ratchet wheel 46 and or engage. When the section associated with the lip 33 has come to rest a little further revolution will restore the equal sides of the chain against the action of the spring 41 and seat the other inner section in the manner shown in Fig. 4.

The wagon h0eZy .-All the members of the wagon bottom are made of sheet'metal, bordered and strengthened by angle iron. The

outwardly flaring top of the wagon box is adapted to be turned down at the sides to make it easier to fill the wagon with material. It is done by unlatching the hooks 22 and the parts when restored to position may besecured by relatching. I claim: 1. In a dumping wagon, a wagon" box having its bottom divided lengthwise into four sections, the two of each pair slidably connected, all of said sections having hinged supports allowing said sections to be swung into the plane of the sides of said wagon box when said bottom is opened, substantially as set forth.

2. In a dumping wagon, a box in combination with two pairs of longitudinally disposed outwardly swinging bottom sections, the inner edge of each of the outer sections resting upon the upper surface of the inner section of the same pair when the parts are at rest.

3. In a dumping wagon the combination with a Wagon box of two pairs of longitudinally disposed, outwardly swinging bottom sections, the outer one of each pair hinged at a point above the surface of the other when in the closed position, and at an angle with it, and means for bodily displacing the inner to throw it into parallelism with the outer when the bottom is dropped, said means comprising angular members each pivoted at one end upon the wagon box and rigidly attached at the other to the said inner bottom section.

4. A dumping wagon comprising a wagon box, two pairs of longitudinally disposed outwardly swinging bottom sections therefor, the outer one of each pair hinged to the side of the wagon body and adapted to be at an angle with the other section when in a closed position, the inner of each pair mounted upon hangers pivotally mounted at points above the outer section when in a closed position and adapted to support the inner edge of the outer section and lie in a horizontal plane.
